The 72 in his five years of racing has evolved while maintaining the basic features.
But I think that an owner of an original chassis and wants to show it with pride, I suppose, must follow the specific version that seeks to restore. Observing the small details too.
For example look the #5 of the Team Lotus Classic or the #7 at the Donington Museum,are perfect.

I fully agree, but also one version could differ at each GP.
